ABSTRACT:
High pressure oxygen is released through a side of an open-ended ventilating bronchoscope or laryngoscope into its lumen in a direction toward a distal end. The oxygen draws air through the proximal end. Medical gasses and vapors are drawn through an entrainment arm at the side of a ventilating endoscope by oxygen which is released near the distal point of confluence of the entrainment arm and the scope lumen.
